Won't Block Good Traffic

Built by Cyber Experts

Stop Cybercrime Before it Hits Your WordPress Website.

Today, your website is your business.

Get our threat blocker plugin and automatically stop harmful visitors from hitting your site – and affecting your bottom line – with things like malware, ransomware, phishing, and botnets.

Our plugin is built on Musubu’s powerful cyber threat intelligence APIs. We collect, score, and type cyber threats by IP address to build you a “WordPress Application Firewall.”

Good traffic gets in, bad guys stay out.

How Can Malicious Traffic Hurt You?

How Does The Plugin Work?

We Score All Visitors

Our plugin uses our Musubu API to dynamically check each IP address that hits your site. Our algorithms and data analysis modules determine if each is a cyber threat, what kind of threat it is, and where it’s coming from.

We Block Bad Traffic

Based on the Threat Score, Threat Type and/or Country of Origin, our plugin blocks traffic that meets certain automatic or manual thresholds from reaching your site. We call it our “WordPress Application Firewall,” or WAF.

You Have Control

You can set our plugin to automatically block traffic that Musubu sees as malicious. That means IP addresses that score higher than 80 out of 100 on our Threat Score range. You can always unblock IPs that you want to allow into your site. Or, you can opt into manual mode and choose what criteria for which to deny access.

Your Site is Safer

Head off connections that lead to “business-killing” things like data breach, phishing, and malware infection before they get inside your walls, and you’ll avoid things like damaged reputation, lost revenue, theft, and costly litigation.

What Are Our Plugin Features?

Powerful Threat Scoring

We collect IP and network threat info 24/7 and then automatically analyze it and score each address from 0-100 (Low to High) as well as show you what type of threat it is (e.g. Ransomware or Botnet).

Real-Time Blocking

We catch incoming traffic to your site and instantly evaluate it for blocking against the Musubu Cyber Threat API algorithms.

Automatic or Manual Mode

“Set it and forget it” to let Musubu’s scoring block any IP with a high Threat Score. Switch to manual to set your own thresholds to block IPs by score, threat type (e.g. Malware or Phishing) or country of origin.

Country Blocking (GDPR)

Use the plugin in manual mode to block incoming connections originating from countries you don’t want hitting your site.

HINT: It’s great for GDPR protections too!
